BOW SIGHT Filed June 26, 1947 Fly? INVENTOR iii/i012 6717mm ATTORNEYPatented July 31 UNITED STATES PATENT OFFICE Bo-W SIGHT Hilton 0. Hamm,East Hampton, Conn. Application June 26,- 1947, Serial No. 757,289 3Claims. (01. 3s- 4e This invention .r'eiatesto archery and particularlyto a bowl'sight'to aid in' accurately sighting the bow at targets atdifferent ranges;

An object of the present invention isto prance a b'ow""s'ight which willenable the target and including a wide field surrounding the target tobe kept in full view during the aiming of the bow and'when releasingthear'row.

A feature that enables the aboveobject to be accomplished v isthatitheprincipal members forming the sighting device are transparentand preferably made of durable sheet material that will not discolorwith prolonged exposure to sunlight.

Another object of the invention is to provide a sighting member havingadjustable opaque sightingpoints thereon, the sighting member beingitself adjustable in a direction normal to the direction of adjustment'of the sighting points.

And finally it is an object ofthe invention to mount the supportingmember-of the-sighting device adjacent the gripping portion of the bowin fixed position while permitting fiexure of the bow during sighting.

With the above and other objects in View the invention may include thefeatures of construction and operation set forth in the followingspecification and illustrated in the following drawing.

In the accompanying drawing annexed hereto and forming a part of thisspecification, I have shown the invention applied to a standard archerybow and disposed in position for a right handed individual but it willbe understood that the invention can be otherwise embodied and arrangedand that the drawing is not to be construed as defining or limiting thescope of the invention, the claims appended to this specification beingrelied upon for that purpose.

In the drawing;

Figure 1 is a perspective view of the central portion of a bow showingthe sighting device in position thereon.

Fig. 2 is a front elevation of the sighting device.

Fig. 3 is a side elevation thereof.

Fig. 4 is a front elevation of a modified form of the invention, and

Fig. 5 is a side elevation of the form Of the invention shown in Fig. 4.

In the above mentioned drawing there have been shown but two embodimentsof the invention which are now deemed preferable, but it is to beunderstood that changes and modifications may be made within the scopeof the appended claims without departing from the spirit of theinvention.

Briefly, and in its preferred aspect, the invention may include thefollowing principal parts: First, a supporting member for thesighting'device attached in fixed position to the bow a short distanceabove the gripping portion of the bow; second, a laterally adjustablemember on the supportingmember; and third, vertically adjustable"sighting points mounted on ,saidlaterally adjustable member.

Referring more in detail to the figures of the drawing, there is shown aconventional or standardf'form of archery bow ill, the central portion,to which the sighting device is attached, only being shown. The bow iiiisprovided with a gripping portion l2 and an arrow plate'i i' as isusual with bows of this type. Justj above the plate Hi and mounted infixed position on the back face of the bow is a supporting member l6 forthe sighting device forming the present in upper and lower horizontallyextending arms 24 and 26, slotted as shown and adjustable relative tothe support by screws or small bolts 28 extending through the slots inthe arms of the sighting member 22 and through suitable holes providedin the support. The sighting member extends obliquely at a slight angleto the vertical and has an elongated slot 38 substantially throughoutits length. This member 22 may and preferably is of rigid durablematerial such as plastic, Plexiglas or other material available in sheetform and is transparent in order not to obscure any portion of the fieldsurrounding the target. Adjustably positioned within the elongated slot3d are sighting spots 32 preferably in the form of small screws adaptedto be readily tightened to maintain them in adjusted position. Theangularity of the elongated slot is relative to the axis of the bow maybe varied by individually clamping the upper and lower arms 2% and 26 tothe support is in different positions along their slots.

In Fig. 4 isshown a modified form of the invention in which a supportingmember 36 is provided with an adjustable cross piece 38. The supportingmember 36 may be secured to a bow in the same manner as the supportingmember is shown in Figs. 1 and 2. An elongated slot #30 extendssubstantially the entire length of the supporting member 36 to permitvertical adjustment of the cross piece 38. To attach the cross piece 38to the supporting member 38 a screw 42, tightened by a Winged nut,passes through the slot 40 and a slot 44 formed in the cross piece 38.The slot M is of sufficient length to permit a substantial transverseadjustment of the cross piece.

The cross piece 38 may preferably be made of transparent materialsimilar to that used in making the member 22 shown in Figs. 1 and 2.

At one end of cross piece 38 is an opaque dot of small size 46 to formthe sighting point. The material surrounding this point 46 is cut awayto provide a substantially open sight. At the opposite end of the crosspiece 38 is a circular portion within the center of which is providedan,

opaque point 48. Spots 45 and 48 may be small metal members attached tothe cross piece '38 or may be formed by painting a small portion of oneof the surfaces of the cross piece.

By vertical and lateral adjustments of the cross piece 38 relative tothe supporting member 36, and reversal of the cross piece 38, eithersighting point 46 or 48 may be adjusted for any range and windconditions. Also either sighting point 46 or 48 enables the entiretarget and surrounding field to be in sight when the arrow is released.

I claim:

1. A bow sight comprising a supporting member adapted for attachment toa bow, a member having spaced apart horizontal slots therein, meansconnecting said last mentioned member to said supporting member by saidslots whereby said last mentioned member may be adjusted laterallyrelative to said supporting member, said laterally adjustable memberhaving a substantially vertical slot formed therein, and sighting pointspositioned adjustably along said vertical slot.

2. A bow sight comprising a supporting member adapted for attachment toa bow in fixed position, a transparent member having spaced aparthorizontal slots therein, means connecting said transparent member tosaid supporting member by said slots whereby said transparent member maybe adjusted laterally relative to said supporting member, saidtransparent member having a substantially vertical slot formed therein,and opaque sighting points positioned adjustably along said verticalslot.

3. A bow sight comprising a supporting member adapted for attachment toa bow in fixed position, a U-shaped transparent member having a centralvertical portion and short upper and V lower horizontal portions ateither end, said end portions having horizontal slots formed thereinwhereby said transparent member may be adjusted laterally relative tosaid supporting member, said transparent member having a substantiallyvertical slot formed along its central portion, and opaque sightingpoints positioned adjustably along said vertical slot.
